Description

Technical Field

[0001] The utility model relates to the technical field of drainage systems for protective engineering, and particularly relates to a modular detachable drainage and wave-dissipating system. Background Art

[0002] When constructing civil air defense projects, it is necessary to comprehensively consider the protection effect of the entire project. The existing explosion-proof and wave-dissipating drainage well disclosed in CN116201979A improves the anti-impact performance of the drainage well by strengthening protection and relieving pressure on impacts. However, its structure is too simple, and its anti-impact and wave-dissipating ability is limited, so it cannot be applied to key protection projects. In addition, the technical solution of the drainage and wave-dissipating device in CN217811444U uses a diffusion chamber and multi-stage valves to block shock waves, and realizes the protection of shock waves through the cooperation of step-by-step blocking and multiple blocking. However, there are problems such as low maximum resistance, long anti-impact process, long reaction time, and low wave-dissipating efficiency. In addition, after bearing a large-pressure impact, some structures of the wave-dissipating device will be damaged by shock waves and need to be replaced and maintained. However, in order to improve the anti-impact performance, most wave-dissipating structures adopt a permanent structure, which is difficult, time-consuming and costly to replace and maintain. The utility model provides a modular detachable drainage and wave-dissipating system to solve the above problems. Summary of the Utility Model

[0037] As Figure 1 、 2 shown, a modular detachable drainage and wave dissipation system includes a maintenance cabin 1, a water inlet pipe 2, a water outlet pipe 3, a high-resistance wave dissipation mechanism 4 and a sub-high-resistance linkage wave dissipation mechanism. The maintenance cabin 1 is buried underground. The maintenance cabin 1 is provided with a water inlet end and a water outlet end. The water inlet end is located at the front end of the maintenance cabin 1, and the water outlet end is located at the lower part of the maintenance cabin 1. The high-resistance wave dissipation mechanism 4, the suspended plate wave dissipation mechanism 5 and the sub-high-resistance wave dissipation mechanism 6 are arranged in the maintenance cabin 1. The suspended plate wave dissipation mechanism 5 is horizontally arranged at the front end of the maintenance cabin 1. The sub-high-resistance wave dissipation mechanism 6 is arranged in parallel in the suspended plate wave dissipation mechanism 5 and is connected to the suspended plate wave dissipation mechanism 5. The water inlet pipe 2 is connected to the sub-high-resistance wave dissipation mechanism 6. The high-resistance wave dissipation mechanism 4 is vertically arranged at the bottom of the maintenance cabin 1. The water outlet pipe 3 is connected to the high-resistance wave dissipation mechanism 4. The drainage direction is from the water inlet pipe 2 flowing in, passing through the maintenance cabin 1 and flowing out from the water outlet pipe 3. The shock wave direction is from the water outlet pipe 3 entering, passing through the maintenance cabin 1 and being transmitted by the water inlet pipe 2.

[0038] Specific embodiments of the present invention achieve shock wave elimination for shock waves with a pressure up to 50 MPa and simultaneously meet the demand for large-flux drainage through the cooperation of the high-resistant shock wave elimination mechanism 4, the suspended plate shock wave elimination mechanism 5, and the sub-high-resistant shock wave elimination mechanism 6; when draining water normally, the water flows in from the water inlet pipe 2, flows into the suspended plate shock wave elimination mechanism 5 after passing through the sub-high-resistant shock wave elimination mechanism 6, the water flows into the maintenance cabin 1 through the suspended plate sleeve 51, the water converges to the water outlet end in the maintenance cabin 1, then flows into the high-resistant shock wave elimination mechanism 4 provided at the water outlet end, and is discharged through the water outlet pipe 3; when an external shock wave enters, the shock wave first impacts the high-resistant shock wave elimination mechanism 4 through the water outlet pipe 3, the high-resistant shock wave elimination mechanism 4 performs a telescopic action under the impact to eliminate the shock wave, and at the same time, the shock wave overflowing from the high-resistant shock wave elimination mechanism 4 enters the maintenance cabin 1 and impacts the suspended plate shock wave elimination mechanism 5 and the sub-high-resistant shock wave elimination mechanism 6. When the shock wave impacts the suspended plate shock wave elimination mechanism 5, it drives the suspended plate shock wave elimination mechanism 5 to close, and at the same time, the sub-high-resistant shock wave elimination mechanism 6 linked to the suspended plate shock wave elimination mechanism 5 synchronously operates for linkage shock wave elimination to eliminate the shock wave. And after the shock wave is eliminated, the high-resistant shock wave elimination mechanism 4 and the suspended plate shock wave elimination mechanism 5 can automatically reset, and the suspended plate shock wave elimination mechanism 5 drives the sub-high-resistant shock wave elimination mechanism 6 to reset to continue normal drainage; the modular high-resistant shock wave elimination mechanism 4, the suspended plate shock wave elimination mechanism 5, and the sub-high-resistant shock wave elimination mechanism 6 are arranged in the maintenance cabin 1 and adopt an underground structure. The maintenance cabin 1 can effectively improve the maintenance convenience, and the modular structure is not only convenient for disassembly, but only needs to replace the damaged structure, which not only ensures the convenient maintenance and replacement between each module, but also further improves the safety and protection of the overall structure.

[0039] As Figure 3 , 5 , as shown in FIGS. 7, further, the high-resistant shock wave elimination mechanism 4 includes a high-pressure outer cylinder 41 and a first telescopic inner cylinder 42. The high-pressure outer cylinder 41 is vertically arranged at the water outlet end of the maintenance cabin 1, and the water outlet pipe 3 is connected to the lower end of the high-pressure outer cylinder 41; the first telescopic inner cylinder 42 is movably arranged in the high-pressure outer cylinder 41 and performs telescopic activities in the high-pressure outer cylinder 41. The first telescopic inner cylinder 42 includes a shielding cylinder 421, a bearing plate 422, an outer cover plate 423, a limiting rod 424, and a reset rod 425. The shielding cylinder 421 and the bearing plate 422 are arranged in the high-pressure outer cylinder 41. The shielding cylinder 421 is arranged below the bearing plate 422 through a connecting rod. The bearing plate 422 is connected to the outer cover plate 423 through the limiting rod 424 and the reset rod 425 and is located below the outer cover plate 423. The outer cover plate 423 is located outside the high-pressure outer cylinder 41.

[0040] As Figure 2 , 3As shown in FIGS. 5 and 7, water outlet and drainage holes are provided at intervals on the barrel wall of the drainage section of the high-pressure outer barrel 41. The water outlet and drainage holes are located inside the maintenance cabin 1. The outer wall of the shielding barrel 421 and the side surface of the bearing plate 422 are both in contact with the inner wall of the high-pressure outer barrel 41. The shielding barrel 421 and the bearing plate 422 are respectively located below and above the water outlet and drainage holes. During drainage, the shielding barrel 421 is located below the water outlet and drainage holes. During shock wave elimination, the shielding barrel 421 moves upward to block the water outlet and drainage holes, and at the same time, the bearing plate 422 seals the inner cavity of the high-pressure outer barrel 41.

[0041] The specific principle of the high-resistance shock wave elimination mechanism 4 for drainage and shock wave elimination is as follows: During normal drainage, the first telescopic inner barrel 42 is in a drainage state under the combined action of the gravity of the shielding barrel 421 and the spring force of the reset rod 425. At this time, the shielding barrel 421 is located below the water outlet and drainage holes of the high-pressure outer barrel 41. The water flow in the maintenance cabin 1 converges at the bottom of the cabin and flows into the high-pressure outer barrel 41 through the water outlet and drainage holes on the high-pressure outer barrel 41, and then flows through the shielding barrel 421 and is discharged through the water outlet pipe 3. When the shock wave impacts the high-resistance shock wave elimination mechanism 4 through the water outlet pipe 3, the shock wave passes through the shielding barrel 421 and directly impacts the bearing plate 422. After the bearing plate 422 bears the impact, it moves upward, driving the entire first telescopic inner barrel 42 to move upward. When the first telescopic inner barrel 42 moves upward, the shielding barrel 421 at its bottom moves upward. When the bearing plate 422 moves upward to the highest position where it is in contact with the buffer pad in the high-pressure outer barrel 41, at this time, the shielding barrel 421 completely shields the water outlet and drainage holes on the barrel wall of the high-pressure outer barrel 41, preventing the shock wave from overflowing for shock wave elimination. When the shock wave disappears, under the combined action of the gravity of the shielding barrel 421 and the spring force of the reset rod 425, the first telescopic inner barrel 42 is pulled downward, and the shielding barrel 421 moves away from shielding the water outlet and drainage holes, and continues to drain water.

[0042] The function of the shielding cylinder 421 is to shield the water outlet and drainage holes on the barrel wall of the drainage section of the high-pressure outer cylinder 41, and at the same time drive the first telescopic inner cylinder 42 to reset downward to the through-flow state by its own gravity; the function of the bearing plate 422 is to bear the impact and drive the first telescopic inner cylinder 42 to move upward, and the bearing plate 422 seals the inner wall of the high-pressure outer cylinder 41, and cooperates with the shielding cylinder 421 to completely seal the inner cavity of the high-pressure outer cylinder 41 to prevent the shock wave from overflowing from the high-pressure outer cylinder 41; the function of the outer cover plate 423 is to limit the first telescopic inner cylinder 42 on the high-pressure outer cylinder 41. The outer cover plate 423 is located outside the upper part of the high-pressure outer cylinder 41 and is connected to the bearing plate 422 through the limiting rod 424 and the reset rod 425, so as to limit the first telescopic inner cylinder 42 in the high-pressure outer cylinder 41 and enable it to perform telescopic actions along the high-pressure outer cylinder 41; the limiting rod 424 plays a limiting role. By cooperating with the linear bearing in the high-pressure outer cylinder 41, the first telescopic inner cylinder 42 performs up and down telescopic actions in the high-pressure outer cylinder 41; the reset spring on the reset rod 425 is always in a compressed state and provides an upward reset elastic force at all times. Its function is that when the impact occurs, the first telescopic inner cylinder 42 can move upward under the action of a smaller impact force. During drainage, the gravity of the shielding cylinder 421 overcomes the spring elastic force on the reset rod 425 so that the shielding cylinder 421 and the bearing plate 422 are respectively located below and above the water outlet and drainage holes to achieve smooth drainage. When the impact occurs, the spring elastic force has a certain auxiliary effect. Since the high-resistance shock wave elimination mechanism 4 needs to resist a high pressure of 50 MPa, the structure of the high-resistance shock wave elimination mechanism 4 is relatively heavy. The reset spring in a compressed state on the reset rod 425 can reduce the impact force value when the first telescopic inner cylinder 42 performs actions.

[0043] As Figure 2 , 4 , and as shown in Figure 6, further, the suspension plate shock wave elimination mechanism 5 and the sub-high-resistance shock wave elimination mechanism 6 perform linkage shock wave elimination. The suspension plate shock wave elimination mechanism 5 is horizontally arranged in the maintenance cabin 1 and is located at the water inlet end of the maintenance cabin 1. The sub-high-resistance shock wave elimination mechanism 6 is arranged in the suspension plate shock wave elimination mechanism 5 and is connected to the cabin wall of the maintenance cabin 1. The front end of the sub-high-resistance shock wave elimination mechanism 6 is connected to the water inlet pipe 2.

[0044] The specific principle of the linked wave dissipation of the suspended plate wave dissipation mechanism 5 and the secondary high-resistance wave dissipation mechanism 6 is as follows: During normal drainage, under the action of the gravity of the suspended plate 52 and the return spring on the limit rod 424 in the second telescopic inner cylinder 62, the suspended plate 52 is opened at this time, and the rear end of the suspended plate sleeve 51 is open. Under the pulling of the suspended plate 52 and the elastic force of the return spring, the shielding cylinder 421 of the second telescopic inner cylinder 62 is located at the rear end of the secondary high-pressure outer cylinder 61, and the water inlet and drainage holes on it are opened. Water flows in from the water inlet pipe 2, flows into the suspended plate sleeve 51 through the water inlet and drainage holes, and then flows into the maintenance chamber 1 through the suspended plate sleeve 51 to achieve the inflow of water; when the shock wave overflowing from the high-resistance wave dissipation mechanism 4 impacts the suspended plate 52, it pushes the suspended plate 52 to swing forward, thereby closing the opening of the shielding cylinder 421. At the same time, the linkage rod connected to the suspended plate 52 drives the second telescopic inner cylinder 62 to move forward synchronously. When the suspended plate 52 is closed in place, the shielding cylinder 421 of the second telescopic inner cylinder 62 completely shields the water inlet and drainage holes on the secondary high-pressure outer cylinder 61 to prevent the shock wave from overflowing for wave dissipation; when the shock wave disappears, under the combined action of the gravity of the suspended plate 52 and the spring force of the limit rod 424 in the second telescopic inner cylinder 62, the second telescopic inner cylinder 62 is pulled backward, and the shielding cylinder 421 allows the shielding of the water inlet and drainage holes to continue drainage.

[0045] As Figure 4 、 6 shown, further, the suspended plate wave dissipation mechanism 5 includes a suspended plate sleeve 51 and a suspended plate 52. The suspended plate sleeve 51 includes a drainage section and an installation section. The installation section of the suspended plate sleeve 51 is fixedly arranged on the inner wall of the maintenance chamber 1 and is directly prefabricated in the chamber during the manufacture of the maintenance chamber 1. The drainage section of the suspended plate sleeve 51 is detachably arranged on the installation section of the suspended plate sleeve 51 to achieve the convenient replacement of the suspended plate sleeve 51 and at the same time facilitate the disassembly and assembly operations of the secondary high-resistance wave dissipation mechanism 6. The suspended plate 52 is movably connected to the drainage section of the suspended plate sleeve 51, and the secondary high-resistance wave dissipation mechanism 6 is arranged in the suspended plate sleeve 51.

[0046] The function of the suspended plate 52 is to block the rear-end opening of the suspended plate sleeve 51, and at the same time use its own gravity to drive the second telescopic inner cylinder 62 to reset backward to the through-flow state. The function of the suspended plate sleeve 51 is to be fixedly connected to the inner wall of the maintenance chamber 1 and form a single-port channel with only the front-end opening of the suspended plate sleeve 51. Water can only flow into the suspended plate sleeve 51 through the water inlet and drainage holes on the wall of the secondary high-pressure outer cylinder 61. When in the wave dissipation state, the front end of the suspended plate sleeve 51 is blocked by the suspended plate 52 for primary wave dissipation, and the water inlet and drainage holes are blocked by the shielding cylinder 421 in the second telescopic inner cylinder 62 for secondary wave dissipation, thereby achieving double wave dissipation of the shock wave.

[0047] As Figure 4 、 6As shown, the second-highest resistance wave-dissipating mechanism 6 includes a second-high-pressure outer cylinder 61 and a second telescopic inner cylinder 62. The second-high-pressure outer cylinder 61 is horizontally arranged at the water inlet of the maintenance cabin 1, and the water inlet pipe 2 is connected to the front end of the second-high-pressure outer cylinder 61. The second telescopic inner cylinder 62 is movably arranged in the second-high-pressure outer cylinder 61 and is located at the rear end of the second-high-pressure outer cylinder 61. The second telescopic inner cylinder 62 includes a linkage rod 621, a linkage cover plate 622, a shielding cylinder 421, a limiting rod 424, and a reset rod 425. The shielding cylinder 421 is arranged in the second-high-pressure outer cylinder 61. The linkage cover plate 622 is located outside the second-high-pressure outer cylinder 61 and at the rear end of the second-high-pressure outer cylinder 61. The shielding cylinder 421 is connected to the linkage cover plate 622 through the limiting rod 424 and the reset rod 425. The front end of the linkage rod 621 is connected to the linkage cover plate 622, and the rear end is hinged to the suspension plate 52.

[0048] As Figure 8 shown, on the barrel wall of the drainage section of the second-high-pressure outer cylinder 61, water inlet and drainage holes are arranged at intervals. The water inlet and drainage holes are inside the maintenance cabin 1. The outer wall of the shielding cylinder 421 fits with the inner wall of the second-high-pressure outer cylinder 61. During drainage, the shielding cylinder 421 is located at the rear end of the water inlet and drainage holes, and the suspension plate 52 is in an open state. During wave dissipation, the shielding cylinder 421 moves forward to block the water inlet and drainage holes, and the suspension plate 52 is in a closed state.

[0049] The function of the linkage rod 621 is to link the suspension plate 52 and the second telescopic inner cylinder 62. When the suspension plate 52 moves, the second telescopic inner cylinder 62 moves synchronously with the suspension plate 52 through the linkage rod 621. The linkage cover plate 622, as the connection structure between the second telescopic inner cylinder 62 and the suspension plate 52, restricts the second telescopic inner cylinder 62 in the second-high-pressure outer cylinder 61 and can perform telescopic movement along the second-high-pressure outer cylinder 61. The function of the shielding cylinder 421 in the second telescopic inner cylinder 62 is to shield the water inlet and drainage holes on the second-high-pressure outer cylinder 61. The reset rod 425 in the second telescopic inner cylinder 62 and the suspension plate 52 work together to drive the second telescopic inner cylinder 62 to reset.

[0050] As Figure 7 、 8 shown, further, both the high-pressure outer cylinder 41 and the second-high-pressure outer cylinder 61 include a drainage section and a mounting section. The drainage sections of the high-pressure outer cylinder 41 and the second-high-pressure outer cylinder 61 are fixedly arranged on the cabin wall of the maintenance cabin 1. The mounting sections of the high-pressure outer cylinder 41 and the second-high-pressure outer cylinder 61 are respectively detachably arranged on their corresponding drainage sections. The high-pressure outer cylinder 41 and the second-high-pressure outer cylinder 61 use the mounting sections to install and limit the first telescopic inner cylinder 42 and the second telescopic inner cylinder 62. The high-pressure outer cylinder 41 and the second-high-pressure outer cylinder 61 use the drainage sections to drain water;

[0051] Further, buffer pads are provided on the installation sections of the high-pressure outer cylinder 41 and the sub-high-pressure outer cylinder 61. The buffer pad in the high-pressure outer cylinder 41 is used to buffer the upward movement of the bearing plate 422 when it receives an impact. The function of the buffer pad in the sub-high-pressure outer cylinder 61 is to avoid direct contact with the sub-high-pressure outer cylinder 61 when the second telescopic inner cylinder 62 moves, playing a buffering role.

[0052] Further, a linear bearing is provided on the limit rod 424. The linear bearing is sleeved on the limit rod 424 and fixedly connected in the installation sections of the high-pressure outer cylinder 41 and the sub-high-pressure outer cylinder 61. The return rod 425 includes a sleeve and a return spring. The return spring is sleeved on the sleeve. The two ends of the return spring on the return rod 425 in the first telescopic inner cylinder 42 are respectively connected to the high-pressure outer cylinder 41 and the outer cover plate 423. One end of the return spring on the return rod 425 in the second telescopic inner cylinder 62 is connected to the sub-high-pressure outer cylinder 61, and the other end is connected to the sleeve of the return rod 425 in the second telescopic inner cylinder 62.

[0053] Further, the rear end face of the suspension plate sleeve 51 is inclined downward. The top end of the suspension plate 52 is movably connected to the suspension plate sleeve 51. During normal drainage, the suspension plate 52 allows the rear end of the suspension plate sleeve 51 to be opened under its own weight. When an impact occurs, under the push of the shock wave, the suspension plate 52 swings upward against gravity to block the rear end opening of the suspension plate sleeve 51. After the impact is eliminated, the suspension plate 52 automatically resets under its own weight to open the opening of the suspension plate sleeve 51 for normal drainage.

[0054] Further, a buffer pad is provided on the rear end face of the suspension plate sleeve 51 to buffer and achieve a sealing effect when the suspension plate 52 is closed by impact.

[0055] Further, a cavity is provided in the suspension plate 52, and the cavity is filled with polyurethane for weight reduction and ensuring impact resistance.

[0056] Further, guide wheels 623 are provided on the shielding cylinder 421 of the second telescopic inner cylinder 62. The guide wheels 623 are spaced at the front end of the shielding cylinder 421 of the second telescopic inner cylinder 62, and the guide wheels 623 are in contact with the inner wall of the sub-high-pressure outer cylinder 61. The guide wheels 623 play a role in limiting the position and assisting the second telescopic inner cylinder 62 in performing telescopic movement.

[0057] Further, the guide wheels 623 are spaced along the circumferential direction of the shielding cylinder 421 to limit the position of the shielding cylinder 421 so that it is located on the axis of the second telescopic inner cylinder 62 and is collinear with the axis of the sub-high-pressure outer cylinder 61.

[0058] As Figure 10As shown in the figure, further, the guide wheel 623 includes a mounting rod and a rolling wheel. The mounting rod is an L-shaped rod. The inner end of the mounting rod is fixed on the inner wall of the shielding cylinder 421 of the second telescopic inner cylinder 62. The rolling wheel is arranged at the outer end of the mounting rod. The rolling wheel includes a wheel body, a mounting pin shaft and a limiting spring. The mounting pin shaft is movably arranged at the outer end of the mounting rod. The limiting spring is sleeved on the mounting pin shaft and contacts the mounting rod. The elastic force of the limiting spring makes the guide wheel 623 always contact the inner wall of the secondary high-pressure outer cylinder 61 and restricts the shielding cylinder 421 to be collinear. The wheel body is located at the end of the mounting pin shaft.

[0059] Further, the linkage rod 621 includes a connecting rod and a hinge seat. The front end of the connecting rod is connected to the linkage cover plate 622. The hinge seat is arranged on the hanging plate 52 and is movably connected to the connecting rod. The linkage rod 621 is used to realize the linkage between the hanging plate wave elimination mechanism 5 and the secondary high-resistance wave elimination mechanism 6, and at the same time, distance compensation is carried out for the swing of the hanging plate 52.

[0060] Further, the maintenance cabin 1 includes a cabin body, fixed supports and a cabin door. The fixed supports are embedded in the underground concrete foundation. Three fixed supports are arranged at intervals. The cabin body is fixedly arranged on the fixed supports. The cabin door is movably arranged on the top of the cabin body, which is convenient for personnel to enter for maintenance and component replacement;

[0061] A water collecting tank is arranged at the bottom of the cabin body. The water flowing in through the secondary high-resistance linkage wave elimination mechanism converges at the water collecting tank and flows into the high-pressure outer cylinder 41 through the water outlet and drainage holes on the high-pressure outer cylinder 41. The high-resistance wave elimination mechanism 4 is arranged at the water collecting tank. A disassembly hook is arranged at the top of the cabin body. An installation hook is arranged on the upper part of the suspension plate sleeve 51 of the secondary high-resistance linkage wave elimination mechanism. The disassembly hook and the installation hook are arranged corresponding to each other up and down, which is used for installing the secondary high-resistance linkage wave elimination mechanism and subsequent maintenance and replacement of damaged components. Since only a manual hoist can be used for hoisting in the cabin, hooks are arranged for connecting the manual hoist.

[0062] The cabin door is of a hollow structure, and a cavity is arranged inside it. The cavity is filled with polyurethane for weight reduction and ensuring impact resistance. The outer shell of the cabin door is a steel shell.

[0063] Further, both the high-pressure outer cylinder 41 and the secondary high-pressure outer cylinder 61 adopt a three-layer composite structure of steel, aluminum foam and steel to improve the compressive capacity.
